Frequently Asked Questions
What should I do if the Master Warning light comes on?
Stop the machine immediately and investigate the cause. Refer to the operator's manual or contact your Bobcat dealer.
How often should I check the engine oil level?
Check the engine oil level daily before operation, especially on the 773, to avoid low pressure warnings.
Can I operate with the Check Engine light on?
The machine may still run, but you risk reduced performance and potential damage. Have it diagnosed as soon as possible.
Why does the transmission temperature light come on during heavy work?
The hydrostatic transmission can overheat under sustained high load. Reduce the load or allow the machine to idle to cool down.
What does the air filter light indicate?
It indicates the engine air filter is restricted and needs cleaning or replacement to maintain engine performance.
Is the glow plug light always on in cold weather?
Yes, it will illuminate during the preheat cycle. Wait for it to turn off before starting the engine.
